SPECIFICATION forming part of Letters Patent No. 422,593, dated March 4, 1890. Application filed Iebruarylll, 1889. Serial No. 2993479. (No model.)

No. 313,593, dated March 10, 1885, wherein a' single camfdisk having projections is rotated l by the said projections striking two rods.

One feature of our invention consists in employing two cam-disks which are geared together, as will be described, so that when one disk is moved in one direction to operate zo one or more cams on the dial cam-plate in one direction-=-such, for instance, as to place .p the dial-needles co-operating with those cams in operative positionthe other diskis moved in the opposite direction to render some or all of the remaining dial-needles inoperative,

as will be described.

The'dial cam-plate will preferably be such as shown and described in another applicat-ion, Serial No. 280,013, filed Julyl 16, 1888.

3o The particular features in which our invention consists will be pointed out in the claim at the end of this specification.

Other features of our invention will be pointed out in the claim at the end of this 3 5 speciiicat-ion.

Figure 1, in elevation, shows a suiiicien-t portion of a knitting-machine embodying our invention to enable it to be understood; Fig. 2, a top or plan view of the machine shown 4o in Fig. 1, with the yoke partially broken out; Fig. 3, aV detail in elevation to more clearly show the ca1n-disks,Which are geared together, the said figure being a side elevation of Fig. 1 looking toward the left; and Figs.A 4, 5, and

6, detail views showing different positions of the cam-disks, as will be referred to.

The cylinder a, carrying the vertical needles, the cam-ring a, carrying the stitch-cams, (not showin) for operating the, vertical nee- 5o dies, the yoke a2, connected to the cam=ring and forming bearings for the vertical spindle a5 of the diahplate a4, and the driving mechanism, consisting of the gears a5 a, pinion a7, ratchet-wheel as, and weighted pawl of', may be substantially such as shown in the patent referred to.. The dial cam-plate a4- is substantially the same as shown in the application referred to, it being provided on its under side with eight sets of cams, each set comprising a drawing- 6o in and a throwing-out cam, four of the said throwing-out cams being made movable and four stationary, and all the drawing-in cams being made movable. Each movable drawing-in cam has connected to it one end of a link b, and each movable throwing-out cam has connected to it one end of'alink b. The

yspindle as of the dial-plate has mounted on it, as herein shown, two rings b2 b3, to which the links -b b are connected to produce plain 7o ribbed work or tuck-work. As shown in the drawings, all the links b are connected to the ring b2 and siX of the links l) connected to the ring b2, and two of the links b are shown'connected to the ring b3. "With the links connected, as shown, a triple tuck may be produced, as described in the application referred to'. The rings b2 b3 have connected to them, respectively, links c c', connected to levers c2 c3, pivoted, as at c4, to a bracket c5", secured 8o to the cam-ring. The levers c2 c3 are respectively operated by means of cams c5 c6 on disks c7 o8, pivoted to the cam-ring. The disks c7 o8 are arranged out lof line with each other and are geared together to work simultaneously 8 5 by gears c0 om, mounted on the pivots of the said gears. The disks c7 o8 are provided with projections c12 c1? c14 015, which are engaged by the rods d d', secured to the levers d2 d3, provided with the studs or projections d4 to be 9o acted upon by the pattern on the patternchain d5. The disks c7 cS are geared together, so that their cams will not act simultaneously on the levers, but only one at a time, as will be described.

As shown in Fig. 1, the cam cE is acting on the lever c?, and the drawing-in cams, connected to the ring b2, are moved inwardly r into their normal or operative position to produce tuck-work, as described in the said aproo plication, while the throwing-out cams, connected to the ring b3, are in their outermost position.

The cam c5 remains in contact with the 1eve c2 untila second cam on the pattern-chain acts on the pin d4, and again raises thc rod d into position to strike the stud or projection c12 and rotate the disks ci c6, through the gears c9 om, from the position shown in Figs. l and 5 to that shown in Fig. G, thus removing the cam c5 from engagement with the lever ci and v engaging the cani cG with the lever c3.

The cani cG remains in engagement with the lever c3 until a cam on the pattern-chain acts on the pin d4 on the levenda and raises the rod d', so as to strike the stud c1B and turn the disks c'Ib cB back into the position shown I in Fig. 5. The disks cs remain in position shownin Flg. 5 until the rod d is again raised into enmay be used instead of a single cam-disk for actuating the thread-guides, substantially as described in the patent referred to, for the production of striped work.

Te claim- The combination, with the dial cam-plate and rings mounted thereon and adapted for connection with the movable cams ot the said dial cam-plate, of the cam-ring', the disks c'cf, pivoted. thereon and provided with gears in mesh with each other to rotate said disks in opposite directions, cams on said disks, levers connected to the rings on the dial-plate, projections on the said disks, rods to engage said projections to rotate said disks, and pattern devices to raise the said rods, substantially as described. l I Y v. l i y In testimony whereof we have signed our namesto this specification in the 'presence of two subscribing witnesses. v
